SPECIFICATION. To all whom it may concer/n:

Be it known that I, HENRY G. KOCHEN- sPERGER, of the town of Thornville,inthe county of Perry and State of Ohio, have made certain Improvementsin Cast-Iron AxleSkeins for Wagons, and in the manner of securing thesaid skeins to the axle; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawing and to the letters of reference marked thereon,in Which- Fignre l is a perspective view of a wagonaxle, showing myskeins; Fig. 2 a viewshowing the lower side of the axle 5 Fig. 3, acrosssection through the section line A B of Fig. 2 5.

Fig. 4, acentral section ofthe skein; and Figs. 5 and o, Cross-sectionsthrough the section lines C Dand E'F of Fig. 4.

My invention relates entirely to axle-skeins,

l which are formed by casting in a mold; and

consists, iirst, in making the under or Wearing side ofthe skein muchthicker than the upper portion; in having lugs cast on the lower side ofthe skeins, by which they are secured to the axle,`and in the strap-boltwhich passes under the axle and ties the skeins together', at the s'ametime affording a bearing for the end of the king-bolt in the front axle,which prevents the head of the bolt froinwearing away the bolster.

lTo enable others skilled in the art to make and use my invention, Iwill proceed to describe its construction.

G is the skein, shown in section in Fig. 4 and in cross-section in Figs.5 and 6. .The casting is cored out so as to leave the meta-l much pthinner on the upper than on the lower or bearing side of the skein, themetal gradually increasing in thickness from the upper to the. lowerside, as shown in the cross-sections, but retaining the same relativethickness through-A 'out its entire length, as shown in the section,

Fig. 4. This forni greatly increases the durability of the skein Withoutinereasin g its weight. H is a strengtheningband or bead formed into alug on the lower side of the skein. The skein is open at both ends, andis therefore more readily cast and fitted to the axle than those inpresent use, which are partially or Wholly closed at the outer end. .heend of the skein is pierced to receivea lineh-pin, as shown' in thedrawing, or a screw is cut on the skein, which is fitted with a nut, orany other device may be used for securing the wheel in its place. I is astrap which passes under the axle, to which it is secured by the bolts aa a a. The ends of the straps are formed into bolts having ascrew-thread cut on them and fitted with nuts. These bolts pass throughthe holes in the lugs H on the 'skeins and tie the skeins together',securing them firmly in their place. The strap-bolt materiallystrengthens the axle, and also gives a bearing for the end of theking-bolt to rest on, as shown in Fig. 3

and set forth above.

What l claim as my invention, and desire to secure by Letters Patent ofthe United States, 1s-

An axle-skein, constructed as described, and having the lug H for theadjustable-attachment of the rod I.
